Protein based molecular markers provide reliable means to understand prokaryotic phylogeny and support Darwinian mode of evolution [PDF]

, 2012
The analyses of genome sequences have led to the proposal that lateral gene transfers (LGTs) among prokaryotes are so widespread that they disguise the interrelationships among these organisms.

Sea Surface Temperature and Salinity Changes in the Easternmost Mediterranean During the Pre‐Evaporitic Messinian Controlled by the Restriction at Gibraltar

Paleoceanography and Paleoclimatology, Volume 41, Issue 1, January 2026.
Abstract During the latest Miocene, the Mediterranean Basin was affected by extreme paleoceanographic and paleoenvironmental changes culminating with evaporite (gypsum and halite) formation during the Messinian Salinity Crisis (MSC: 5.97–5.33 Ma).

Confounding effects of oxygen and temperature on the TEX ₈₆ signature of marine Thaumarchaeota [PDF]

Proceedings of the National Academy of Sciences, 2015
Significance Ammonia-oxidizing archaea (AOA) are among the most abundant microorganisms in the ocean. Apart from having a major influence on the nitrogen cycle, the glycerol dibiphytanyl glycerol tetraether (GDGT) membrane lipids of AOA are widely used to reconstruct past sea surface temperatures.

Microbial diversity in the deep-subsurface hydrothermal aquifer feeding the giant gypsum crystal-bearing Naica mine, Mexico

Frontiers in Microbiology, 2013
The Naica mine in Northern Mexico is famous for its giant gypsum crystals, which may reach up to 11 m long and contain fluid inclusions that might have captured microorganisms during their formation.

Species-level functional profiling of metagenomes and metatranscriptomes. [PDF]

, 2018
Functional profiles of microbial communities are typically generated using comprehensive metagenomic or metatranscriptomic sequence read searches, which are time-consuming, prone to spurious mapping, and often limited to community-level quantification ...

Desert pavements: A hidden key to Earth surface processes

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
Desert pavements are a global phenomenon in arid environments, representing one of the most extensive geomorphological and geoecological features on Earth. To a large extent, they determine the interplay of key processes governing current and past landscape dynamics.

Horizontal gene transfer of a chloroplast DnaJ-Fer protein to Thaumarchaeota and the evolutionary history of the DnaK chaperone system in Archaea

BMC Evolutionary Biology, 2012
Background In 2004, we discovered an atypical protein in metagenomic data from marine thaumarchaeotal species. This protein, referred as DnaJ-Fer, is composed of a J domain fused to a Ferredoxin (Fer) domain. Surprisingly, the same protein was also found

Abundance, classification and genetic potential of Thaumarchaeota in metagenomes of European agricultural soils: a meta-analysis

Environmental Microbiome, 2023
Background For a sustainable production of food, research on agricultural soil microbial communities is inevitable. Due to its immense complexity, soil is still some kind of black box.

Stepwise Cooling Events in the Western Arctic at 8.2 and 4.2 ka: Proxy Development and Application

Paleoceanography and Paleoclimatology, Volume 40, Issue 12, December 2025.
Abstract Hydroxylated glycerol dialkyl glycerol tetraether (GDGT)‐based proxies have recently been proposed for reconstructing sea surface temperatures (SSTs) in polar oceans, but their reliability has not yet been sufficiently validated. We investigated the spatial distribution of hydroxylated GDGTs in surface sediments from the western Arctic Ocean ...

Characteristics of Wetting-Induced Bacteriophage Blooms in Biological Soil Crust. [PDF]

, 2019
Biological soil crusts (biocrusts) are photosynthetic "hot spots" in deserts and cover ∼12% of the Earth's terrestrial surface, and yet they face an uncertain future given expected shifts in rainfall events.
